Skeleton King first kill no rare loot

Killed the Skeleton King first time with new character and dropped no rare loot besides Demonic Essence.

I created a new wizard on Hardcore and killed the Skeleton King on Master Difficulty for the first time and did not recieve any rare weapons or armor. He dropped two blue items and a Demonic Essence. I do not know if the Demonic Essence counts as a rare loot drop but I recall getting two rares on live for each first boss kill. This was done on the PTR in solo Hardcore Master Difficulty with a wizard.
